Glycolysis Flashcards
What type of reaction is catalyzed by phosphofructokinase?
Phosphoryl transfer
Where does the citric acid cycle take place?
The citric acid cycle (Krebs’ cycle) occurs within the mitochondria of eukaryotic cells.
How many turns of the Krebs cycle does it take to completely oxidize 1 glucose?
Two turns since glycolysis normally produces 2 pyruvate.
What must be present for both the Krebs cycle and the electron transport system to function?
Oxygen
What is the maximum number of ATPs you can get from 1 mole of glucose?
38
Where does the Krebs cycle and the electron transport reactions occur?
In the mitochondria
Excluding any products of glycolysis or the electron transport system, what are the final products of a single turn of the Krebs cycle?
4 NADH, 1 FADH, and 1 ATP.
If the electron transport system isn’t working, how many ATPs can glycolysis and the Krebs cycle produce?
4 ATP
If glycolysis is working correctly and the Krebs cycle and electron transport system are not used, what are the final products produced?
2 ATP, 2 NADH, and 2 Pyruvate
What type of reaction is catalyzed by glyceraldehyde- 3 phosphate dehydrogenase?
Phosphoryl transfer
What type of reaction is catalyzed by phosphoglucose isomerase?
Isomerization
What type of reaction is catalyzed by phosphoglycerate kinase?
Phosphoryl transfer
What is the starting product for the Kreb’s cycle and what compound is necessary for its formation?
AcetylCoA which is formed from pyruvate.
What type of reaction is catalyzed by hexokinase?
Phosphoryl transfer
What is oxidative phosphorylation?
Oxidative phosphorylation describes a series of electron transfers that lead to the formation of adenosine triphosphate. Oxidative phosphorylation is responsible for about 90% of all oxygen consumed in the body.
